Annual reconstitution of Russell's U.S. indexes captures the 4,000 largest U.S. stocks as of the end of May, ranking them by total market capitalization. Membership in the Russell 3000 means automatic inclusion in the large-cap Russell 1000® Index or small-cap Russell 2000® Index as well as the appropriate growth and value style indexes. The Russell 3000 also serves as the U.S. component to the Russell Global Index, which Russell launched in 2007.

"We are very pleased about our addition to the Russell Indexes, a notable step in our progress as a publicly traded company," President and CEO, Jeffrey Eckel commented. "We welcome the opportunity to increase awareness about Hannon Armstrong and broaden our shareholder base."

Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. Widely used by investment managers and institutional investors for index funds, the Russell indexes also serve as benchmarks for both passive and active investment strategies. Approximately $4.1 trillion in assets are benchmarked to the Russell Indexes. Based on Russell's procedures, membership in each index remains in place for one year.
